Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This rectified my knowledge of how to solve absolute value inequalities. Thanks you Sir Khan!
It helps a lot..Thank You!!
I'm so sad bcs of the pandemic we have to study online. Most of my teachers doesn't even teaching us properly but giving us such a bunch of works 😭
sorry Ananda , most students are going through the same thing but hey that's why we have Khan Academy
I think I might pass the math test I have on this today. I actually understand some of it. Thanks Mr.Khan!
Carson.Cristine. did you pass?

In Soviet Russia, student teach teacher.
i took a test in algebra 1 and it had a lot of inequalities. i took a gamble because i was confused on which way to do it and there were 2 in my head. i knew only one of them was right. i did all them this way! :D phew. thanks sal. great vid. if inequalities come up again ill know for sure.
Why not simplify things by stating that |x| < a is equivalent to -a < x < a?
Thank you Mr. Man
That's not the way common core taught us and the way we do it gets a different answer
you're my new hero Mr.Khan!
I know you would respond but ur really great
Wouldn't*
@@andrewdineros1313 Bro... I think you can edit a comment 😄
I'm not sounding rude...
Godd!! I'm having trouble with fractions! I also need to learn for Chemistry! I know. that's weird. Sucks 4me. wth happened?
Are you still alive
3*1/4 is 3/4 not 13/4 , if it was 3 + 1/4 the answer in the video would be right but there is nothing to indicate that its 3 + 1/4

No.
3 1/4 is another way of saying 13/4. It is not3*1/4. It was taught in elementary school.
I have a tutoring job tomorrow for this I have no idea what I’m doing 😬
than why did you sign up ._.
